Q WPJM UNITED STATES ATENT AUGUST STEPHAN, OF BREITENBACH, GERMANY.

APPARATUS FOR MAKme s ze SPEGIFIGATION forming part of Letters Patent No. 648,887, dated May Application filed March 20, 1899.

To coZZ whom it may concern:

Be it known that I, AUGUST STEPHAN, a sub-' ject of the German Emperor, residing at Breitenbach, Alsace, in the German Empire, have invented certain new and useful Improvements in Apparatus for the Continuous Treatment of Size, (for which I have applied for patcuts in Canada, (la-ted September 21, 1898; in France, dated January 23, 1899; in Austria, dated January 23,1899 in Switzerland, dated January 23, 1899; in Hungary, dated January 26, 1899; in Belgium, dated January 27, 1899; in England, dated January 30, 1899; in

Italy, dated Febru'ary'13, 1899; in Germany, dated February 9, 1899; in Russia, dated February 18, 1899, and in Japan) of which the following is a specification.

'My-invention-relates to apparatus for the. continuous treatment of size; and it consists of the improvements which are fully set forth in the following specification and are shown in the accompanying drawings;

:In such apparatus as now in use the raw material is stirred or agitated within the boiler; but there is no separation within the boiler of those portions of the mass which have alreadybeen boiled and treated from the freshly-entering portions.

It is the object of this invention-to effect such aseparation of those portions of the raw material whichhave already been treated or which the material is discharged after treatment.

Vvis the rotary'shaft within the cylinder or chamber R, which carries the usual agitating or stirring-devices.

- S is a disk fitted on the shaft V, of which one or more may be used,.disposed between the inletY and outlet Hand dividing the cylinder or chamber R internally into two or Serial No. 709,772. (lie model.)

more compartments, of which the first communicates with the inlet Y and the last with the outlet ll. Communication is afforded between the compartments through the dis S either by a space between the periplirny of the disk and the inner surface of the R or by holes or perforations t. {See Fig, In Fig. 1 .Ihave shown a single disk. :3 of smaller diameter than the cylinder It, so as to form an annular space for the passage of the material. The raw material enters through the inletY and is stirred or agitated within the compartment-on one side of the disk S and is finally forced by the pressure of the incoming materialv through thespace about the disk S into the compartment on the other side of the disk,where it is further treat- .ed, and is finallgiorced out, through theoutlet I-l. Thus the materialwhich has been ar tially treated and forced beyondthe disk S is prevented by the disk, which'acts as apartition, from passing back and mingling again with the freshly-entering portions of raw material, and consequently a more uniform treat ment is effected.

In the construction shown in Fig. 2 I have employed a series of disks or partitions'S, of which part are of the full diameter'of the cylinder R, but are provided with openings or perforations t, and apart are of less diameter, similar to the partition or'disk S of' Fig. 1. In this construction the perforated disks and the disks of small diameter are-alternated.

The minor details of construction may be varied Without departing from the invention.

What I claim as new, and desire to secure by Letters Patent, is-

1. In apparatus for the continuous treatment of size, the combination of the closed boiling-cylinder, the agitator-shaft arranged. therein, and one or more dividing-partitions within said cylinder of a diameter approximately equal to that of the interior of the boiling-cylinder, but having passage-ways of restricted area,-dividing the boiling-cylinder internally into a series of compartments having restricted iuterc'ommuuiea tion for the passage of the material; substantially as and for the purposes described.

2. In apparatus for the continuous treatment of size, the combination of the closed boiling-cylinder, the agitator-shaft arranged therein, and one or more dividing- 1artiti0ns within said cylinder, of a diameter approximately equal to but slightly less than the interior of the boiling-cylinder, dividing the cylinder internally into a series of compartments haying a restricted intereommunicati on for the passage of the material, substantially as and for the purposes described. a

Inapparatus for the continuous treatment of size, the combination of the closed boiling-cylinder, the agitator-shaft arranged therein, and a series of dividing-partitions within the cylinder dividino' it intern "11v 1 to aseries ofv compartments, part of said partiing provided with perforations, whereby a restricted intereommunication between said compartments is afforded for the passage of the material.

, In testimony whereof I have hereunto set my hand in the presence of two Witnesses.
